The user provides arbitrary non-numeic value to level and type, which could bring unexpected behavior. In this case the expected behavior would be to throw an error. pfrut -h usage: pfrut [OPTIONS] code injection: -l, --load -s, --stage -a, --activate -u, --update [stage and activate] -q, --query -d, --revid update telemetry: -G, --getloginfo -T, --type(0:execution, 1:history) -L, --level(0, 1, 2, 4) -R, --read -D, --revid log pfrut -T A pfrut -G log_level:0 log_type:0 log_revid:2 max_data_size:65536 chunk1_size:0 chunk2_size:1530 rollover_cnt:0 reset_cnt:17 Fix this by restricting the input to be in the expected range.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
